what do you do?? To service your 4 wheel drive.
 

Its about to start snowing around here I bought my truck used a few months ago. I figured I would change the front and rear diffs. And the transfer case. Are there any grease fittings or other things you guys do??

I've got grease fittings on my universals to grease. But yours are probably sealed- Otherwise I change all the fluids in my drivetrain including transmission every two years or about 40,000 miles. But I always check all of my 4 wheel drive fluid levels every oil change. They have very little fluid in them to begin with so any leak can lead to damage.

Where and what are the 4 wheel drive fluids you check and change?? is the just the differential, transfer case, and trans fluid?
